I’d recommend asking this kind of question on stackoverflow in future, but you can do that with:
b = (a .reshape((2, 2, 4, 4)) # split up the (4,) axis into (2, 2) .transpose((2, 0, 3, 1)) # reorder to (4, 2, 4, 2) .reshape((8, 8)) # collapse adjacent dimensions ) On Tue, 22 May 2018 at 21:31 Yu Peng <ypeng...@gmail.com> wrote: > Hi, I want to make an opreation like this: > > if I hava a matrix: > > a= > > array([[[ 0, 1, 2, 3], > [ 4, 5, 6, 7], > [ 8, 9, 10, 11], > [12, 13, 14, 15]], > > [[16, 17, 18, 19], > [20, 21, 22, 23], > [24, 25, 26, 27], > [28, 29, 30, 31]], > > [[32, 33, 34, 35], > [36, 37, 38, 39], > [40, 41, 42, 43], > [44, 45, 46, 47]], > > [[48, 49, 50, 51], > [52, 53, 54, 55], > [56, 57, 58, 59], > [60, 61, 62, 63]]]) > > > and the shape of a is (4,4,4), I want to tranform this tensor or matrix > to (8,8), and the final result is like this: > 0 16 1 17 2 18 3 19 > 32 48 33 49 34 50 35 51 > 4 20 5 21 6 22 7 23 > 36 52 37 53 38 54 39 55 > 8 24 9 25 10 26 11 27 > 40 56 41 57 42 58 43 59 > 12 28 13 29 14 30 15 31 > 44 60 45 61 46 62 47 63 > If you know how to deal with this matrix, please give me some > suggestions..
